Summary:This adds a `HEIGHT` constant on `StatusBar` on Android. I needed only this for now but I will work on a better status bar dimensions API later (see TODO). It also improves the implementation to fix a bug that happened when multiple `StatusBar` components get updated in the same frame as well as remove useless calls to the `StatusBarModule` when values did not change. Instead of calling the `StatusBarManager` immediately when the component gets updated and relying on the order of the calls that get dispatched to native we now wait at the end of the frame to send the calls to the `StatusBarManager` using `setImmediate`. To make this work properly we need to change the data structure of the props stack a little bit to store the desired transition/animation too for each value. Finally this updates the example to only show the ones that work for the current platform. **Test plan** In the UIExplorer Example, in the 'StatusBar dimensions' section it should show 25 for the height of the status bar.

UIExplorer
The UIExplorer is a sample app that showcases React Native views and modules.
Running this app
Before running the app, make sure you ran:
git clone https://github.com/facebook/react-native.git
cd react-native
npm install
Running on iOS
Mac OS and Xcode are required.
- Open
Examples/UIExplorer/UIExplorer.xcodeprojin Xcode - Hit the Run button
See Running on device if you want to use a physical device.
Running on Android
You'll need to have all the prerequisites (SDK, NDK) for Building React Native installed.
Start an Android emulator (Genymotion is recommended).
cd react-native
./gradlew :Examples:UIExplorer:android:app:installDebug
./packager/packager.sh
Note: Building for the first time can take a while.
Open the UIExplorer app in your emulator.
See Running on Device in case you want to use a physical device.
Built from source
Building the app on both iOS and Android means building the React Native framework from source. This way you're running the latest native and JS code the way you see it in your clone of the github repo.
This is different from apps created using react-native init which have a dependency on a specific version of React Native JS and native code, declared in a package.json file (and build.gradle for Android apps).
